Neural Activity
Forgetting is an important and natural process, but what does forgetting look like in the brain?  To investigate this question, we test participants' memory while measuring brain activity using tools such as electroencephalography (EEG) and functional magnetic resonance imaging (fMRI).  In order to have a better understanding of how context is represented in the brain, and how it may shift/drift, we have to measure not just global changes in neural activity, but also changes in distributed patterns of activity.  To this end, we use advanced techniques such as multivariate pattern analysis (MVPA) and representational similarity analysis (RSA) to examine neural activity of brain patterns.  We additionally use frequency tagging in EEG, a technique to tag a stimulus with a particular neural signal, to probe how specific contextual details may be reactivated or forgotten in a memory experiment.
